  • Hydrodynamic characterisation of an airlift reactor for domestic wastewater treatment

    This study evaluates the hydrodynamic and mass–transfer behaviour of a 20–L airlift photobioreactor, employed for secondary wastewater treatment of domestic effluent. Gas hold–up (ε), as well as the volumetric mass transfer coefficient (kLa) was assessed as a function of superficial gas velocity (Ug) for both bi– and triphasic systems. In the experimental range of Ug ...

  • Air New Zealand: facing increased competition

    Due to globalisation of other airlines, Air New Zealand (NZ) faces increased competition on domestic routes. The Australian flag-carrier Qantas (QF) flies within New Zealand; yet, Air New Zealand has no routes within Australia. Likewise, Pacific Blue (DJ) flies within New Zealand, previously the domain of Air New Zealand. Dubai-based Emirates (EK) takes passengers across the Tasman Sea, but Air ...

  • Preliminary study of osmotic membrane bioreactor: effects of draw solution on water flux and air scouring on fouling

    Preliminary study on a novel osmotic membrane bioreactor (OMBR) was explored. Objective of this study was to investigate the effects of draw solution on membrane flux and air scouring at the feed side on fouling tendency in a pilot OMBR system composing the anoxic/aerobic and forward osmosis (FO) processes. Domestic sewage was the raw feed, FO membrane from HTI and NaCl/MgSO4 draw solutions were ...

  • 2010 predictions

    Our thoughts are below on what may be headed our way in 2010 from the U.S. Environmental Protection Agency's (EPA) Office of Prevention, Pesticides, and Toxic Substances (OPPTS). In short, the momentum and positions that the Obama Administration took in 2009 are likely to become greater and more solidified in 2010 as a number of key issues are addressed. EPA as a whole continues to exhibit a ...

  • Update and revision of Turkish air quality regulation

    The Air Quality Assurance Regulation (AQAR) was issued on October 1986. This regulation was basically a direct translation of the German TA-Luft of 1984. The main purpose of AQAR was to control the effect of industry, domestic heating and Traffic on ambient air quality which previously had not adequately been represented. Two new regulations, "Industry Related Air Pollution Control Regulation" ...

  • ADMS-Urban: an air quality management system for traffic, domestic and industrial pollution

    The new version of the Atmospheric Dispersion Modelling System for urban environments, ADMS-Urban, is based on the same up-to-date physics as the ADMS model, outlined briefly here in Section 2. The basic model has been the subject of extensive validation studies: as part of this series of European Harmonisation Workshops; sponsored by HMIP (Her Majesty's Inspectorate of Pollution, now part of the ...
